Calculate the number of isomeric halopropanes produced, when propane gets chlorinated is:

Options

A. 1
B. 2
C. 3
D. 4

Explanation

To determine the number of isomeric halopropanes produced when propane is chlorinated, we can follow these steps:

### Step 1: Understand the Structure of Propane
Propane is an alkane with the molecular formula C₃H₈. Its structure can be represented as:
- CH₃-CH₂-CH₃

### Step 2: Identify the Chlorination Reaction
When propane undergoes chlorination (reaction with Cl₂), hydrogen atoms in the propane can be replaced by chlorine atoms. This process is known as free radical halogenation.

### Step 3: Determine Possible Positions for Chlorination
In propane, there are three carbon atoms:
1. The first carbon (C1)
2. The second carbon (C2)
3. The third carbon (C3)

Chlorination can occur at any of these carbon atoms.

### Step 4: Identify the Isomeric Products
1. **Chlorination at C1**:
- The product formed is 1-chloropropane (CH₂Cl-CH₂-CH₃).

2. **Chlorination at C2**:
- The product formed is 2-chloropropane (CH₃-CHCl-CH₃).

3. **Chlorination at C3**:
- The product formed is also 1-chloropropane (CH₂Cl-CH₂-CH₃), which is the same as the product from C1.

### Step 5: Count Unique Isomers
From the above analysis, we find:
- 1-chloropropane (from C1 and C3)
- 2-chloropropane (from C2)

Thus, there are **two unique isomeric halopropanes** produced when propane is chlorinated.

### Final Answer
The number of isomeric halopropanes produced when propane is chlorinated is **2**.
